BINDER.

Specification of Letters Patent.

Application filed April 29, 1919. Serial No. 293,378.

To all whom it may concern:

Be it known that I, CARL E. ANDERSON, a citizen of the United States,and a resident of East Orange, county of Essex, and State of New Jersey,have invented certain new and useful Improvements in Binders, of whichthe following is a specification.

This invention relates to an improved binder and is of that type knownas a temorary binder, being adapted to receive folded sheets where theyare folded and hold them in position.

The invention provides a .binder which does not necessitate perforatingthe sheets for receiving rings or other fixtures for fastening thesheets'in position, being adapted to receive folded sheets which can beremoved from the binding element either edgewise or from the bottom.

The invention is further designed to provide a binder which can besecured to a cover at the back thereof so as to hold the sheets betweenthe covers, the binder being adapted to be secured to the covers whenthe book is made, or it can be used as an attachment and secured by anyone to the back of the covers, as will be understood.

The invention consists further in details of construction and inproportioning the parts and providing securing means which will behereinafter more fully described and finally embodied in the clauses ofthe claim.

The invention is illustrated in the accompanying drawings, in whichFigure 1 is a topview of my improved to the cover and having sheets inplace. Fig. 2 is a section of the cover and a part of the binder, themajor portion of the sheets and of the binder being shown in elevation.Fig. 3 is an enlarged end view of the binder. Fig. 4: is a perspectiveview of a modified form of construction. Fig. 5 is a detail perspectiveview of a latch used in the construction shown in Fig. 1. Fig. 6 is anend view of the structure shown in Fig.4, but with the strands of wireheld in binding position. Fig. 7 is a View similar to Fig. 6, butshowing a still further modified form of construction, and Fig. 8 is aside view of the type of binder shown in Fig. 7.

To make the-use of the invention clear I have illustrated it within acover having the flaps or cover portions 10 and 11 connected by a coverback 12. It will be understood that this cover is not essential. to theinvenbinder fastened :very thin material,

metal, and in order stiffness it is provided with longitudinal ribstion, but it is usually preferred, and the illustration shows it inorder to enable any one to fully understand how the device can be usedwith such covers.

The binder consists of a backing 18, which is substantially long andnarrow and is adapted to be secured tothe back by means which arepreferably designed to make it detachable, in the form shown consistingof prongs 14 which are preferably struck up from the metal of which thebacking is made and are folded over, as clearly shown in Fig. 2, so asto clamp the device to the back of the cover, thereby stiffening theback and also holding the backing of the binder in position on thebackof the cover.

The sheets 15 of paper are held in folded position, the folds 16 beingpassed over suitable strands 17 and 18, and while one strand may beused, I have illustrated and" prefer to use two strands, which areprovided by a wire that is bent double, the bent portion serving as ameans by which they strands are pivoted to the backing. In the formshown, the wire forming the strands 17 and 18 is bent at 19, thisconnecting part being secured in an eye 20 that is bent up from the endof the backing 13, being usually bent slightly out of line with thebacking so as to permit the back 12 of the cover to lie flat. The freeends 21 of the strands are held down so that the strands aresubstantially parallel with the backing when they are in bindingposition.

One type of such fastening means comprises hooks 22 which are formed inthe lip 28, bent up from and integral with the backing 13. The backing13 is usually made of preferably thin sheet to give it the required 2 1,and to stiffen the lip 23 it is usually provided with a ribbed part 25.In order to give the necessary amount of spring to cause the ends 21 ofthe wires to snap under the hooks 22 1 form the strands, as at 26, neartheir pivotal ends, the strands at this point being bent down so thatthey contact at the part 26 on the ribs 24 and thus cause a springaction on the ends 21, as will be readily understood from an inspectionof Figs. 2 and 3.

This binder can be attached to any suitable form of cover, and thesheets 15, which are not necessarily perfQrated, can be folded PatentedJan. 6, 1920.

of the lip in, being placed edgewise around the wire,

or they-can be folded and then slipped onto strands is preferred becausethere is less bulky folding at the back of the note book or folderformed by the sheets, and part of the sheets can be replaced or removedwith out disturbing the other sheets held by the other strand.

In Figs. 4, 5 and 6 I the strands 17 and 18 being bent down, as at 27,so as to form the part 2-8 to swing in the eye 20, the backing 13.having the end opposite the eye 20 a lip 29 provided w th T-shapedslots 30, the upper ends of which form the hooks 31 under which the ends21 of the strand are caught. The top surface 29 is rounded, as at 32. Alatch 33 with notches 38 in its top edge extends across the lip and isnormally held slightly above the hooks 31 by the spring lip 3i, which ispreferably made integral with the latch 33and is fastened, as by a rivet35, to the backing 13.

This structure facilitates the placing of the wires into bindingposition and also holds the wires against accidental removal.

1 'The wlres are bent down and they engage the rounded surfaces 32, andthe thumb and forefinger, pressing down on the wires, hold them inposition, but the wires, being secured at the rounded corners 32 againstthe pressure of the fingers, engage the top edge 36 of the latch 33,which is pressed down against the action of the spring lip 3d, and thepressure of the fingers snaps the wires into position when they arriveopposite the openings 37 of the if-shaped slots 30, and when the wiresare released, the notches combine with the sides of the T-shaped slotsto guide the spring wires to the locked posi tion illustrated in Fig. 6.

To strengthen the parts and also to assist in holding them in alinement,the lip 29 is preferably provided with a rib 39 and the latch 33 isprovided with a rib 40, these be :ing in register when the parts areassembled and preventing lateral movement of the latch relative to thelip.

In Figs. 7 and 8 I show a still further modified form of construction,the backing and the lip 29 being the same as shown in Figs. 4, 5 and 6,but the latch is provided with an extension 41, the top 42 of which isadapted to form a finger piece so that the atch can be pushed down whenit is desired to release the wires 17 and 18 from the locked positionshown in these figures, and the finger piece can also be manipulated topermit the insertion of the wires, but to facilitate this insertion Iprefer to incline show a modified form,

'of the strands when the sides of the latch 33 upward and inward, as at43, so that by slight pressure of the wires the latch is pushed downwarduntil its top edge is below the openings 37 of the T-shaped slots 30,and the wires can then pass into such slots and under the hooks 31.

The latch is preferably provided with a rib ll which is in register withthe rib 39 of the lip 29, thus preventing any undue side movement of thelatch relative to the lip and permitting the use of one rivet or similarfastening means 35.

The binder herein described can be made of very thin sheet metal andtherefore is very light in weight and is very economically made,requires but little material, at the same time providing a binder thatis positive in its operation and extremely simple in construction.

I claim:

1. A binder comprising a long narrow sheet metal backing bent at one endinto an eye and at. the other end into a member shaped to form a pair ofhooks, and a wire doubled so as to form a pair of strands having aconnecting part swinging in the eye, the free ends of the strands beingadapted to be caught under the hooks.

being bent near the eye so that the strand engages one of the ribs togive the end of the strand a tension when it is bent down to the 5. Abinder comprising a backing being bent at one end into a member shapedto form a pair of outwardly turned hooks, a wire bent double to form apair of strands, the bent portion being pivoted to the end of thebacking opposite the hooks, the free ends or" the strands being adaptedto engage the hooks to be held down thereby, a latch normally closingthe hooks and having a spring lip thereon, the end of the lip beingsecured to the backing.

6. A binder comprising a backing being bent at one end into a membershaped to form a pair of outwardly turned hooks, a wire bent double toform a pair of strands, the bent portion being pivoted to the end of thebacking opposite the hooks, the free ends of the strands being adaptedto engage the hooks to be held down thereby, a latch normally closingthe hooks and having a spring lip thereon, the end of the lip beingsecured to the backing, and a projection on the latch extending abovethe hook to form a finger piece for the manipulation of the latch.

7. A binder comprising a sheet metal backing being bent up at one endwith its opposed edges provided with T-shaped slots forming hooks andhaving a rounded top portion, a latch against the inner side of the bentportion and having a spring lip extending therefrom and secured to thebacking, the latch being wider than the hook portion and normally heldabove the openings of the T-shaped slots, and a pair of strandspivotally attached to the end of the backing opposite the bent upportion, the free ends of the strands being adapted to enter the slotsand to be held therein against movement away from the backing.

In testimony that I claim the foregoing, I have hereto set my' hand,this 28 day of April, 1919.

CARL E. ANDERSON.
